The next featured gadget in our 2011 Holiday Gift Guide is the Twelve South PlugBug. It's a device that's so simple that it's hard to believe no one has come up with this until now. The PlugBug snaps onto your MacBook, MacBook Pro, or MacBook Air wall charger, giving you a powered USB port in the process. The results? You can then charge both your Apple notebook, and a USB device (like an iPhone or iPad) at the same time, using just one outlet. Genuis! This means that when you're on the go, you can carry one less charger, and you'll have one less outlet to try and find. You can get the PlugBug on Amazon for $34.
